Your question does not make sense. Your descendants are your kids, grandkids, etc. Hopefully you will know your kids.

If you mean ancestors (meaning your parents, grandparent, etc), then you will have to do genealogy research. Many things can be found on the internet, but not all of it.........and it won't all be free.........and if you find where someone has already done some research on your family tree because their family tree intersected with yours, don't assume it is accurate. Ask them where they got the information. Was it from primary sources (birht/marriage/death certificates; census records, wills, deeds, etc) or did they just copy and paste from someone else. Any copying and pasting is not research.....it is just name collecting. If that is all they are doing, then copying the local phone book is more accurate than what they are doing.

There is a lot to know, but you will learn as you go.

Its easy with modern technology. Just got to a descendant clinic and they will do some tests and tell you who they are.

Its simple math.

People who come after you? or people you decended from? There are implantable micro chips just put one in each child Just like the Vet does your dog.
